Unc-In

The biological cousin that moreso performs or holds the role of an Uncle than a cousin to you.

Comes from the blending of Uncle + Cousin (Unc from Uncle + In from Cousin)

Originates from the Midwest USA in 2020.

Hey, my Unc-In is going to drop us off at the game. Who? My cousin, but he's old enough to be my Uncle.

Unc

A crazy, old black man. Uncs are usually senile or under the influence of crack cocaine. Sometimes both.

There was an unc screaming at himself outside of Waffle House so I went to Golden Corral instead.
